PT2000 Programmable Gate Driver Freedom Platform

The KITPT2000FRDM3C evaluation board (EVB) allows you to exercise all the functions of the PT2000 direct injection pre-driver circuit. A PC communicates through USB to the EVB through a FRDM-KL25Z freedom board used as a SPIdongle. The Freescale SPIGen (version 7.0 and above) program provides the user interface to the PT2000 SPI port and allows the user to program the Code RAM and Data Registers, send commands to the IC and receive status from the IC.
